# Base Image EOL Lint - Dockerfile and CI end-of-life check

Marks every base image in your Dockerfiles, compose files and CI workflows whose security patches have already stopped - or stop before 13 November 2026 - and prints the tag that replaces it.

Runs entirely in your browser. Nothing is uploaded, nothing is stored.
